ORCHARD-HEATER.

Specification of Letters Patent.

Patented June a, 1914.

Application filed mama- 24, 1914. Serial No. 820,429.

To all whom it may concern:

Be it known that I, James L. HAMILTON, a citizen of the United StatesofAJnerica, and-resident of Grand J unction, county of Mesa, and Stateof Colorado, have invented certain new and useful Improvements inOrchard-Heaters, of which the following is a specification.

This invention relates broadly to orchard heaters; and it has for itsprimary object to provide a heater of the oil-burning type havingimproved means for increasingits efiiciency as a producer of heat.

A further object of the invention is to pro vide an orchard heaterot thecharacter mentioned having separate means supplying air to the interiorof the oil container and to the lower portion of the stack for mixingwith the gases arising from said container, and provided with meanswhereby both of said air supplies are regulated by a single adjustment.

A still further object is to provide a heater in which is attainedcombustion of such a character as will, in a large measure, if notwholly, obviate the production of soot or carbon, and, consequently,prevent the collection of the carbon deposits which so frequently clogthe draft perforations of such devices, detrimentally affecting theiroperation, if not rendering them wholly inefficient.

Another object is to provide a heater in which heated air is intreducedto the stack in such manner as to produce a high order of carburation ofthe gases.

A further object within the contemplation of the invention is to providean orchard heater whereingis employed a plurality of separate andindependent stacks arranged in a cluster.

With these and other objects in view, the invention resides in thefeatures of construction, arrangement of elements and combinations ofarts which will hereinafter be exemplifi reference being bad totheaccompanying drawings, forming apart of this specification, in which-'Figure 1 is a top plan view of the invention; Fig. 2 is a longitudinalsection on the line 2-2, Fig. 1; Fig. 3 is a cross section on the line3-.-3, Fig. 2; Fig. 4 is a view similar to Fig. 1, illustrating amodification; Fig. 5 is a longitudinal section on the line 5-5,

Fig. 4:; and Fig. 6 is a cross section on the line 66, Fig. 5.

lteferrmg to said drawings, in which like designating charactersdistinguish like parts throughout the several views-J indicates an oilcontainer which may be of any suitable shape, but which is hereinillustrated as rectangular. Mounted upon said container is a cover 2 ofupwardly dished form, to which a flat plate or diaphragm 3 is attached,as by seating the edges of said diaphragm within the embraoe'of aperipheral outwardly directed crimpor fold 4 formedin saidcover adjacentto its lower lateral edges. Provided on said cover 2 at a suitable pointis an elevated portion 5 of frusto-conical form, as is clearly shown inFig. 2. The upper open end of said portion 5 closely embraces the bodyof an upright stack 6 which has its lower end seated within an opening 7provided therefor in the underlying diaphragm 3. Provided in the cover 2at a point laterally of the elevatedportion 5 is a circular openin 8 inwhich 15 fitted the upper end of a tu e 10 the body of which isprojected through an opening 9 in the diaphragm, said tube being adaptedto admit air to the interior ofthe container for mixing with the gasesarising from the fuel contained in the latter, and having one or moreside-openings 11 provided therein below the point em braced by saiddiaphragm for permitting air to pass to said contamer even though itslower end be submerged in the oil, as shown in Figs. 2, 8, 5 and 6. Saidtube is preferably detachable, having an annular flange 12 formed atits-up or end adapted toseat upon the cover 2. rovided in said coveradjacent to the upper end of the tube 10 is a circular row oferforations 13 through which air may be a mitted to the passage 14formed between the body of said cover and the diaphragm. As shown, theperforations 13 reglster with similar perforations provided in theoverlying flan e 12; but, as is apparent said flange may o made of suchless width that it will not overlie the said perforations 13. A damper15 of ap ropriate form, pivoted on the cover 2, is a apted to beadjusted to close the mouth of the tube 10 and the said perforations 13to any desired extent for simultaneously regulating the air supplyadmitted to the container and to the passage 14:, the latter being inopen communication with the annular chamber 16 which is constitutedbetween the stack 6 and.

theelevated port-ion 5. Numerous small perforations 17 provided in thestack at polnts 7 intermediate the diaphragm and the point been found tobe advantageous in that a more thorough commingling therein of theintroduced air with the gases is effected than is possible in a singlelarge stack.

Before reaching the apertures or perforations 17 in the stack,the airadmitted to the passage 14 becomes heated from contact with thediaphragm 3 and cover 2. This heated air, introduced to the stackthrough said perforations, commingles with the gases arising from thecontainer, resulting in a mixture which burns with a clear hot flame andwithout disengaging particles of carbon. As

is well known, the introduction 'of air direct from the atmosphere intoa stack near its base'is attended by various obj ectionableresuits,chief among which is the deposit/of carbon on the walls of the stack,said carbon being the result of condensation due to imperfect combustionof the gaseous mixture. In other words, the cold air so introduced doesnot unite with the gases to produce proper combustion, but tends toproduce a condensation of carbon, particles of which adhere to theinterior walls of the stack and to the edges of the perforations to suchan extent that saidperforations quickly become clogged and entirelyclosed, in which condition they of course fail to perform their intendedfunction.

The introduction of heated air thrbugh the perforations, as hereinbeforeindicated, obviates the freeing of the carbon, the stack remains clearand clean, and the apertures or perforations are left wholly free frontcarbon deposits.
